APPARATUS FOR G EN ERATING ACETYLEN E GAS.

$PEUIFICATION forming part Of Letters Patent NO. 696,418, dated April 1,1902. Application filed June l2 1897. Serial No. 640,474. (No model.)

To all whom it may concern:

Be it known that I, EDWARD N. DICKER- SON, of the city, county, andState of New York, have invented new and useful Improvements inApparatus for Generating Acetyleue Gas, of which the following is aspecification.

The present invention relates to improvements in apparatus forgenerating acetylene gas.

} The special object of the invention is to provide a simpleconstruction for generating acetylene gas, in which construction thecalcium carbid is made in the shape of a cylinder and the supply offluid thereto for generating the gas operates to cause the carbidcylinder to present new surfaces to which the fluid is applied in theoperation of generating the gas.

In the drawings I have shown a construction which embodies theinvention, in which Figure 1 is a central vertical section, certainparts being shown in full. Fig. 2 is a section along line 2 2 of Fig. 1.

In the several views of the drawings like figures of reference refer tolike parts.

Referring to the drawings in detail, 1 represents a suitable receptacle,which is here shown as cylindrical. This receptacle is divided into twocompartments 2 and 3, the compartment 2 being situated above thecompartment 3 and holding the supply of fluid.

The compartment 3 is provided with a door 4 at itsside, which is capableof hermetically closing said compartment. A cylinder of carbid 5,mingled with a suitable agglomerating agent, as is now well known, issuitably supported in the compartment 3. As shown in the drawings, thecylinder is supported by cap-pieces 6,provided with journals 7, mountedin standards 8 and 9, the standard 9, situated nearest the door 4 in thecompartment 3, being removably mounted, so as to permit of the carbidcylinder being withdrawn and a new one placed in position. A diaphragm10 divides the receptacle into compartments 2 and 3 and is provided withan opening, communicating with which opening is a flexible tube 11,extending downwardly into the compartment 3. The lower end of thisflexible tube carries a transverse pipe 12, provided with aperturesthrough which the fiuidis supplied to one side of the carbid cylinder 5.

13 designates a cock for drawing oif the gas generated in the operationof the device.

The operation of the device will be obvious. Fluid is gradually admittedthrough the flexible tube and transverse pipe to the side of the carbidcylinder, thus causing the generation of acetylene gas. When thepressure of the gas exceeds the desired amount, the flow of waterceases, or other well-known regulating devices may be employed. Therefuse matfor from the carbid cylinder falls upon the bottom of thereceptacle, thus diminishing the weight on that side of the cylinder. Bythe action of gravity the cylinder then will rotate slowly in thedirection of the arrow and correspondingly to the amount of gasgenerated and the refuse thrown off from the cylinder, thus continuallypresenting a new surface to be acted on by the fluid-supply from thecompartment 2.

I do not limit myself to the exact form or device here shown,intendingto covenbroadly, presenting fresh surfaces of oarbid to a disintegratingfluid by reason of the movement of the carbid affected by the diminutionin weight, consequent upon its partial destruction.

What is claimed as new is- 1. In a gas-generating apparatus, thecombination with a generating-receptacle, of a solid gas-gen eratin greagent rotatably mounted within said receptacle, and means for applyinga second reagent upon one side of said solid reagent, and therebydecompose the latter in such manner that it will rotate by gravity andpresent other parts of its surface to the action of said second reagent,substantially as described.

2. In a gas-generating apparatus, the combination with a receptacle, ofa solid reagent rotatably mounted therein, a flexible conduit incommunication with a fluid-supply, and a perforated tube supported byand in communication with said conduit and adapted to supply fluid toone side of said solid reagent, and thereby decompose the latter in suchmanner that it will rotate by gravity and present other parts of itssurface to the action and present other parts of its surface to the ofthe fluid, substantially as described. actionofsaidfluid,substantiallyas described. 3.
